Abstract
The utility model is a medium hot air furnace applicable in metallurgy above 250m <3>. This hot air furnace comprises a hanging chain type vault structure, a two-section type heat sponge chamber, a cold wind evenly collocating device and a high temperature-keeping furnace body. The heating area of this heat air furnace is 2 to 4 times of that of Ball type heat air furnace. The heat conduction coefficient of the heat air furnace is 10 times of that of regular checker bricks. Besides, the heat sponging time is longer and the dead-corner is prevented in the heat sponging chamber. This heat air furnace can save a plenty of energies and investment cost while in utilization. Besides, the safety performance is high and the maintenance cost is low. The device is good for popularization.
Description
Affiliated technical field
The utility model relates to a kind of energy-efficient metallurgy hotblast stove.
Background technology
The hotblast stove of metallurgy industry mainly adopts Cowper stove and two kinds of forms of pebble stove now, Cowper stove is lower because of its heat storage capacity, production unit heat institute consumed energy is higher, replaced by pebble stove just gradually, the patent No. is that 96224018.4 hotblast stove has solved the highly energy-consuming problem, but because its whole body of heater bottom is designed for V-type, the manufacturing cost and the manufacture difficulty of hotblast stove have been strengthened, there is certain potential safety hazard, and when sending hot blast, have the dead angle phenomenon in the stove, cause partly heat energy difficulty send.
Summary of the invention
For the highly energy-consuming problem that solves present Cowper stove and the deficiency of the patent No. 96224018.4, the utility model provides a kind of hotblast stove, this hotblast stove can not only effectively reduce energy consumption, can also reduce cost of goods manifactured, improve Product Safety, and can eliminate the dead angle phenomenon that exists in the body of heater, at utmost the heat energy in the regenerator is sent.
The utility model technical scheme that is adopted of dealing with problems is: the vault construction of pebble stove is the catenary vault, and ball bed regenerator is made of high and low temperature two-section type ball bed, and ball bed regenerator is cylindrical, is provided with the cold wind even distribution device in the body of heater bottom.When gas when burner port burns, its heat energy will by the ball bed three high balls, siliceous ball, high aluminium ball absorbs and save, after being heated to required temperature, close burner port, prepare hot wind supply, freezing air enters from the flue gas mouth, through entering regenerator behind the cold wind even distribution device, to directly be heated by the ball in the ball bed when time in the freezing air process regenerator, freezing air becomes warm air, sends from hot-air mouth subsequently.
The beneficial effects of the utility model are, can improve thermo-efficiency, and product-specific investments is few, and is simple in structure, the safety performance height.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is the utility model cross-sectional view;
Accompanying drawing 2 is the fire grate front elevation;
Accompanying drawing 3 is a cold wind even distribution device front elevation;

Embodiment
This utility model integral body is cylinder shape, cylinder-shaped top is a dome-shaped, in order to reach high insulation purpose, inner high alumina brick (7) and the outside insulation brick (11) that adopts of adopting of the body of heater of this hotblast stove piled up, wherein high alumina brick (7) thickness of laying bricks is 300mm, insulation brick (11) thickness is 400mm, can effectively reduce the heat lost by radiation of body of heater, improves thermo-efficiency; In order to reach the uniform technical requirements of the gentle distributions of Stability Analysis of Structures; vault construction is two circular fitting formula catenary vaults of catenary vault; the inner high alumina brick (7) that adopts of vault; the outside light cinder brick (6) that adopts of high alumina brick (7); the vault thickening is 900mm; high alumina brick (7) and light cinder brick (6) respectively account for 450mm, spray the thick unshape refractory of 50mm (5) again at light cinder brick (6) skin, play the protection furnace shell and strengthen insulation effect.In order to prevent the furnace wall differential expansion vault masonry is produced destruction, the direct rest of the masonry of catenary vault is on furnace shell, and furnace wall top adopts " labyrinth type " (non-substantivity) coulisse to be connected with vault knot platform place, effectively to prevent gas leakage.When gas when burner port burns, its heat energy mainly concentrates on the upper half part of ball bed, according to the temperature height ball bed regenerator is divided into two-section type ball bed, (3) spheroid produces bonding because of contact stress and high temperature creep for fear of the high-temperature zone, the technical barrier of distortion, therefore in high-temperature zone (3), fill three high balls of three micro mists or siliceous ball, can effectively absorb heat energy and high temperature resistant, in cold zone (2), fill the high strength high aluminium ball, to reach the manufacturing cost that when not influencing accumulation of heat, reduces hotblast stove, the bottom of body of heater is provided with the fire grate of heat resisting iron processing and fabricating (13) to bear the spheroid of ball bed regenerator, the body of heater bottom is cold wind even distribution device (14), when sending hot blast, cold wind gas enters from flue gas mouth (1), through form uniform distribution behind the cold wind even distribution device in the bottom, upwards successively enter ball bed regenerator (2) and (3) then by fire grate, because the regenerator of body of heater is vertical cylindrical, therefore freezing air enters Shi Buhui and has the dead angle phenomenon, can fully absorb the heat energy that each ball is saved in the regenerator, freezing air is heated by ball and sends from hot-air mouth outlet (4) immediately.
